What about including the xindy FAS files in the distribution?
FAS files are plain text ASCII files and compress well.
One can even concatenate them (in the right order) and gzip.
Then upgrading CLISP would mean re-dumping the lisp image (MEM):
clisp -i xindy.fas -x '(saveinitmem "xindy.mem")'

(Another alternative is distribute an executable image with xindy.
This way it no longer depends on the version of the current CLISP
installation.)

In my experience lisp image portability is nil.
There is very little chance that any effort will ever be saved by
upgrading CLISP and checking that the existing image is compatible with
the new CLISP. It is safer and cleaner to _always_ re-dump the MEM file
from FAS.gz distributed with the package.

I think this is what Bruno meant by his ls.so analogy.

Thanks.
